2. Queries about the language policy as a science teacher  What is the purpose of using English to teach science?  Would the use of English as the MOI hinder students’ understanding of science?  Does the use of English as the MOI involve the teaching of English language?  Does the teaching of English language imply a decrease in the teaching time of science?  How to motivate students to learn science through English?

3. “If we teach a subject which students find difficult, boring and unappealing, and if on top of that, students are being taught in a language they find difficult, then for them to learn anything is going to be a miracle.” (Deller and Price, 2007)

4. Inspirations from “Doing, Talking and Writing Science” 1.Science is a cultural construct  Scientists communicate in specific genres: purposeful, predictable, objective, logical, systematic  Genres convey thinking patterns, and are hence ways of constructing knowledge.  Teaching science is guiding students to think in specific generic ways: experimental reports, descriptive reports, sequential explanations, analytical arguments, etc.

5. Inspirations from “Doing, Talking and Writing Science” 2.Learning is from receptive knowledge to productive knowledge  It is in the transition from receptive knowledge to productive knowledge that conceptualization begins.  Productive knowledge is an authentic assessment of students’ learning.  Teaching is guiding students from the engagement in texts (doing, speaking, listening, reading, viewing) to the organization of knowledge and then to the production in writing.

6. Changes in teaching practices 1.From texts to notes  Using various types of graphic organizers, tables, charts or diagrams to represent different genres.  Different genres require different types of organizers.  Guiding students to organize their own notes.  Examples: F. 1 I.S. NotesF. 1 I.S. Notes

7. Changes in teaching practices 2.From speaking to writing  Guiding students to formulate their understanding into sentences and paragraphs, giving necessary language supports.  Helping students to link up their paragraphs into passages.  Examples: F.1: Supply and demand of petroleum fractionsSupply and demand of petroleum fractions F.3:Balanced diet & Short writingsBalanced dietShort writings
